Thylakoid A thylakoid is a membrane-bound compartment inside chloroplasts and cyanobacteria. They are the site of the light-dependent reactions of photosynthesis. Thylakoids consist of a thylakoid membrane surrounding a thylakoid lumen.Chloroplast thylakoids frequently form stacks of disks referred to as grana (singular: granum).n higher plants thylakoids are organized into a granum-stroma membrane assembly. A granum (plural grana) is a stack of thylakoid discs. Chloroplasts can have from 10 to 100 grana.

Chloroplasts Inside the chloroplasts are stacks of discs called thylakoids. They are compared to stacks of coins within the walls of the chloroplast, and they act to trap the energy from sunlight. The stacks of thylakoids are called grana.They are connected with an extensive sytem of tubules. The thylakoid membranes contain chlorophyll and other pigments arranged in antenna arrays to capture light energy for two photosystems called Photosystem I and Photosystem II.lants use energy from the sun in tiny energy factories called chloroplasts. Using chlorophyll in the process called photosynthesis, they convert the sun's energy into storable form in ordered sugar molecules such as glucose.

What are analogies for chloroplasts? What is going on inside the chloroplasts? The chloroplast is like a tiny bag with even smaller flattened bags called thylakoids inside it.You could compare the chloroplast to a factory with two crews (PSI and PSII) inside the thylakoids making batteries and delivery trucks (ATP and NADPH) to be used by a third crew (special enzymes) out in the stroma.

- The water compartment inside the thylakoid membrane is called the lumen. The water area outside of the thylakoid, but still within the chloroplast, is the stroma. Photosynthesis occurs in two sets of reactions that are linked by electron carrier molecules (NADP + /NADPH) and ADP/ATP. The two reactions go by several names.

What Is the Role of Chloroplasts? Quick Answer. Chloroplasts are the sites of photosynthesis in eukaryotic cells. They capture sunlight and store the light energy in the form of adenosine triphosphate and nicotinamide adenine dinucleotide phosphate molecules. Chloroplasts play a role in carbon fixation, fatty acid synthesis, amino acid synthesis and the immune response of plants.

Chloroplast Chloroplasts, like mitochondria, contain their own DNA, which is thought to be inherited from their ancestor—a photosynthetic cyanobacterium that was engulfed by an early eukaryotic cell. Chloroplasts cannot be made by the plant cell and must be inherited by each daughter cell during cell division.

Thylakoid Membrane in Photosynthesis: Definition, Function & Structure Definition and Function of Thylakoid Membrane. The thylakoids themselves contain the chlorophyll, but the thylakoid membrane, which is the layer that surrounds the thylakoid, is where the light reactions take place. Embedded in the thylakoid membrane are two photosystems, named photosystem I and photosystem II.

Chloroplast Light travels as packets of energy called photons and is absorbed in this form by light-absorbing chlorophyll molecules embedded in the thylakoid disks. When these chlorophyll molecules absorb the photons, they emit electrons, which they obtain from water (a process that results in the release of oxygen as a byproduct).

However, within this membrane is yet another series of folded membranes that form a set of flattened, disklike sacs called thylakoids. The space enclosed by the inner membrane is called the matrix in mitochondria and the stroma in chloroplasts.

Chapter 06 - A Tour of the Cell Chloroplasts capture light energy and convert it to chemical energy. • Chloroplasts contain the green pigment chlorophyll as well as enzymes and other molecules that function in the photosynthetic production of sugar. • Inside the innermost membrane is a fluid-filled space, the stroma, in which float membranous sacs, the thylakoids. The stroma contains chloroplast DNA, ribosomes, and enzymes. The thylakoids are flattened sacs that play a critical role in converting light to chemical energy. In some regions, thylakoids are stacked like poker chips into grana. • The chloroplast belongs to a family of plant structures called plastids.

Are chloroplasts found in animal cells? No, animal cells do not contain chloroplast because chloroplast functions as the source of photosynthesis. Chloroplast is part of the Plastid group, which are specific organelles which specifically function in organic plant organisms. This group, in general, supplies the energy storage and the synthesis of metabolic materials, e.g. photosynthesis.
